A TTORNE Yf Patented Feb. 9, 1932 UNITED STATES ARTHUR L. BOIBRICK, OFLOS ANGELES, CALIFORNIA SOAP DISPENSER Application led April 9, 1930.Serial No. 442,804.

This invention comprehends the provision of an improved type of soapdispenser, preferably adapted for dispensing liquid soap, and includingimproved means for irremovably supporting a dispenser on a wall orsupporting surface, and a valve mechanism for dispensing the soaptherefrom which is bodily removable from the receptacle.

Another object is to provide in a soap dispenser, a receptacle, adispensing valve mounted on the receptacle, means for attaching thedispenser in position for use, and means rendered edcctive by theassembly of the valve on the receptacle for irremovably locking thereceptacle in position, except by authorized persons.

Another object includes the provision of a suitable key adapted for usefor authorizedly removing the receptacle when desired.

Another object is to provide a specially formed attachment plate held onthe rear of the receptacle and arranged to irremovably hold thereceptacle in position for use on a supporting member, together with animproved type of filling cap and means for attaching the same to thereceptacle.

Other objects may appear as the description progresses.

In the accompanying drawings I have shown a preferred form of myinvention subject to modification within the scope of the claims,withoutdeparting from the spirit thereof.

In said drawings,

Fig. 1 is a perspective view of a dispenser embodying my improvements,as seen from the rear side thereof.

Fig. 2 is an enlarged sectional elevation of the same on line Q--Q ofFig. 1.

Fig. 3 is a transverse section of the dispensing valve on line 3 3 ofFig. 2.

Fig. 4.- is a perspective view of the key suitable for attaching andremoving the valve from operative position.

Fig. 5 is a transverse section of the attaching means for the dispenseras seen on line 5--5 of Fig. 1.

Fig. 6 is a section of the filling cap on line t-G of Fig. 2.

In its preferred form my dispenser includes a sheet metal receptacle 1of suitable form and provided with an enlarged encompassing base portion2 and a front vportion 3 within which is a single compartment 4 adaptedto contain a quantity of soap. The compartment 4 is closed by a pan likebottom 5 which is welded or otherwise suitably attached to the flatportion 6 of the base, and has an encompassing flange 7 which issimilarly secured to the flange 2 of the base. The bottom thus nestssnugly in and is irremovably secured to the base 2 and provides ashallow compartment 8 inwardly of the bottom which is closed on its rearside by the surface of a wall or supporting surface 9, to which thereceptacle is adapted to be attached for use.

Centrally of the back or bottom 5, I provide a vertical attaching plate10 which has a foot 11 on its upper end adapted to be welded orotherwise permanently secured to the back, while the portion of thestrip below the foot is bent outwardly and is spaced slightly from theback 5. The lower end of the strip 10 is right-angularly bent outwardlyat 12, and intermediate the portions 11 and 12 a pair of bayonet slots13, 13 are formed in the strip 10. Said slots have enlarged circularextremities 14 at their bottoms and elongated portions 15 at their tops.The portions 14 are of suliicient size that the heads 16 of screws 17may be inserted therethru into the space between the back 5 and theplate 10. A pair of longitudinal ribs 11', 11', are formed in the plate10 so as to render the plate rigid, as hereinafter explained.

When the receptacle is forced downwardly over the heads of the screws 17the bodies of the screws will seat in the upper extremities of theportions 15 of the slots while the heads will seat in conicaldepressions 18, as seen in Fig. 5, which are formed at the upper ends ofsaid slots.

The ribs 11 on the attaching plate 10 serve to strengthen the platelongitudinally so as to prevent the buckling of the plate intern mediateits ends and to uniformly engage and support the receptacles on thescrew heads 16. 1Were said ribs omitted the plate would bend in themiddle to such an extent that it would be possible to detach thereceptacle from the screw heads and the ribs are safeguards against suchan act. l

Near the bottom of the receptacle 1 I provide a dispenser valve which ismounted partly within and partly without the compara` ment 4 on thefront19 of the receptacle. Said valve includes an internal barrel likebody which is closed at its inner end bymeans Vof a screw 21 which istightly threaded into the rear end 20 thereof. Said Vscrew extends thruapertures in the back 5V and plate 10 and is preferably provided with asquare or"heX agonal head 22 positioned adjacent the portion 12 of plate10 so that one of the flats on lthe head wil-l tightly fit against theportion -12ofthe plate. rlhus thescrew 21 is prevented from turninginthe members 5 and Y .apart,wherebythe soap fromcompartment 4 may enterthe cylinder 23.` The rear end 2O ofthe barrel 2O has an outer endportion 2G which projects thru and substantially outwardly from the.front wal-l 19 of the receptacle and is externally threaded, as shownin Fig. 2. The valve further includes a cup shaped cap27 which has acylindrical body 28 with Va bore 29 therein. kSaid bore is vclosed atthe outer end of the cap by means of a wall 30, and a conical iiange 31is provided at the inner end ofthe cap which rests against the frontwall 19 of the receptacle. The'invner portion of bore 29 is internallythreaded at v532 to receive the externally threaded portion 26 .of thebarrel 20. The flange 31 en- 'closes and compresses a washer 31 againstthe front 19 of the receptacle and also radially aroundthe'portion 26 ofthe valve bar-V rel, and thus prevents leakage.

Vlvhenthe valveis being assembled, the barrel 20 is'tightly screwed intothe cap 27 with -a cage 33 and washers 34 and 34 interposed between theouter end of the barrel andthe wall .as shown. Cylinder 23, however, hasa lpiston 35 reciprocally'mountedtherein and urged outwardly to the endof the cylinder' .by means of acompression spring 35 which is held incompression between thepiston and tthe portion 20 of the barrel. Saidpiston ihas astem 36 riveted or otherwise permanent- .ly attached.thereto, which extends r thru a -bore37of cage 33 and a correspondingbore in theendBO ofthe cap. Y

A suitable knob orfiiange-SSS is formed von or attached to the stem36and serves as an operatingA member for the piston. Thus, when thepiston is forced inwardly against 'the 'tension of spring 35 until itreaches a Jposit-ion intermediate the orifices 24 and'25 of 'thecylinder', the liquid from compartment 4V offthe receptacle Vwill enterthat portion of "the cylinder outwardly of the piston, and the tensionof spring 35 when pressure on the member 38 is released will restore thepiston to its normal position, as shown in Fig. 2.

The stem 36 just forwardly of piston 35 is provided with a wide annulargroove 39 which forms an annular compartment in the boreV *37y of member33 when the piston is in normally outward position. The cage 33 -also.has an annular groove formed therein to provide a chamber within thecap 27, and said 4chamberhas a single outlet 41 on thelower side of thecap. The chambers 39 and 41 are permanently in communication by meanso'fvone or more orifices 42 formed in the cage 33, as shown in Fig. 2.Thus when vthe Apiston is forcedinwardly -to va maximum extent theforward end "of thecylinder 23 is charged with a quantity of liquid fromthe compartment 4, and the ensuing outward -movement of the pistonforces said chargev of liquid into the'bore 37 of the cage and thenceoutwardly thru orifices 42 into chamber 40, and finally outwardly thruthe single orifices f41 inthe cap. When the piston is forced inwardlyagainst Ythe-tension of spring 35 any liquid which is present in thecylinder A23isevacuated thru orifices 24and 25.

In assembling Vthe dispenser, when the dispenser l isloosely mounted onthe heads 16 of screws 1'?, as hereinbefore described, theV piston,piston stem, and cage are then mount- ;ed in the cap 27, whereupon thebarrel 20 is tightly screwed into the cap so that it will be incapableof removal therefrom except Vby authorized persons orby persons who are:familiar with the manner of assembly. The assembled dispenser valve isthen bodily insertedthru'the aperture in the receptacle 1 and turnedin agiven direction so asy to screw 4the barrel20tightly upo'ntthe screw 21.Y

When this is done the tightening of the screw 21on the barrel 2O willdraw the plate 10 tightly against the back-5 or awasher 43, which may beinterposed between the back Vand the plate, so that itwill be impossibleto move the receptacle over the heads of screws '17 Aand thereforeimpossible to remove the receptacle from the supporting surface 9without unscrewing the cap 27. Neither .the

members 20 or27 are provided with flats or means for attachment ofordinary'wrenches or implements thereto, whereby said members may beunscrewed. The washer 43 prevents leakage of the soap aroundthe bolt 21.j

The outlet/41 ofthe cap, however, protrudes substantially from theperiphery of 'the cap and provides a means of attachment for a specialtype of wrench 44, which'may be applied to the cap for removing it.V,Said

nwrench is lshown in Fig. 4, and in brokenlines l in Fig. 3, andincludes ahandle 45'w1th a hook 46 formed at one end thereof adjacent arecess47. y

Vhen the wrench is applied to the cap 27 for attaching or removing thesame from operative position the hook Li6 is inserted in the outlet l1while the recessed portion 47 rests against the periphery ot the cap. Asseen in F ig. 3, when the wrench is turned in a clockwise direction itwill tightly screw the cap 27 into operative position on the receptacle.Uien the wrench is placed in a reverse position on the cap it may beemployed ttor unscrewing the cap.

The vibrations 4G and 46 of the wrench l5 may also be employed as a gagefor setting the screws 1G so that the heads of the screws will bepositioned at equal distances from the .tace of the supporting member 9.In such case the recess 1li" between said vibrations engage the bodiesoil the screws 1G and the screws are then screwed into the member 9 sothat the heads will engage the outer surface ot the wrench.

The receptacle l may be filled with liquid thru a sleeve 48 which isirremovably held in the top i9 ci' the receptacle. Said sleeve .has aspring held cap 50 enclosing the upper end thereof, which is mounted ona hinge pin 50. rihe sleeve has an annular reduced portion. l whichengages the opening in the top i9, and also embraces a flange 52overlying the top oit the receptacle.

'.lhe sleeve below the portion 5l is normally straight so that it may bereadily inserted in the opening' in the top and is then rolled annularlyand expanded at 53 so as to underlie the top of the receptacle toprevent the removal et the iilling cap. rI'he top L i9 of the receptaclemay be provided with a plurality oi recesses i9 around the openingtherein so Athat when the portion is expanded the recesses 4:9 will bepartially iilled with the metal forming the annular portion 5B so as toin'event the turning of the cap in the top.

llrom the foregoing description of my imprfrvements it will be observedthat I have provided a simple, e'llective, and economical dis'iensingmechanism tor liquid soap or for other materials which is ordinarilyincapable oiE removal for extracting the contents thereoit' witlmutlinowledge of its manner of assembly and possession of the special typeof wrench tl-fi necessary for suoli purpose. In any event, one seekingto remove the receptacle in an unauthorized manner must know the secretoi the combination between the several elements which combine to holdthe case in position on the surface 9 and to remove the .ip Q7 from thereceptacle.

While I have shown a suitable form of valve for use in connection withmy receptacle, it will be understood that any other suitable torni oi'valve may be employed. The essential characteristics oiE the valve aresuch that the valve may be bodily assembled, inserted in and removed'from the receptacle, and that the valve may not be removed by theapplication oit an ordinary wrench or tool, 'for the reason that aspecial type ot' wrench is required. The opening il which receivedp0rtion 46 of the wrench is so formed that a nail or other straight toolwill not be eilective for turning the valve cap :28. rlhe washers 3l and43 prevent leakage of the contents thru the openings for the valvebarrel and the bolt 21.
